To fulfill the homeowner's rigid and elastic everyday needs, the roughcast house without partitions is turned into a dream home after rearranging the traffic flow. Without an over-decorated design, the purity of gray and white refines the residence. The gradient earth colors and wood tones gradually create rich layers in a single dimension. By eliminating fixed frames and walls, the house owner has the flexibility to move furniture around and adjust the direction at will to enjoy the sunshine. A human-centered approach is the core of interior design.
